"mpath dump" of iw does not show mop paths. If you assigned addresses of the same IP subnet to mesh1 and eth@router, and can ping the eth address, mesh1 probably has a correct path. > Another point is that I have to add a line like this in any mesh node to work: > "route add default mesh_interface", it works but I think is not correct > because you use level 3 (is there another way to do it?), I get ping from > node 1 to eth port of the router (good) but if I try to ping from node 1 to > internet (8.8.8.8) I get no answer, and wireshark shows in eth port of router > that node1 is arp-broadcast asking who has 8.8.8.8., ther router don't send > the packets to internet.
